Light Yagami is the main protagonist of the manga series Death Note, created by Tsugumi Ohba and Takeshi Obata. He is portrayed as a brilliant but bored genius who finds the Death Note, a supernatural notebook that allows the user to kill anyone by knowing their name and face, after it is dropped by the Shinigami Ryuk.
